Information

Installation File

The installation file installs all necessary files for using the software on your Windows system. The installation file can also be installed over an already existing version of the software. The existing application data and settings are automatically adopted.

Update File

The update file allows you to update an existing installation of the software. No new program shortcuts in the Start menu or on the desktop are created or updated during this process. The existing application data and settings are automatically adopted.

ZIP

The installation file is packaged in a ZIP archive. After downloading, you can either extract the file with a right-click or open the archive directly in Windows Explorer and start the installation by double-clicking the EXE file.

Digital Signature

You can verify a file's digital signature by right-clicking on a file and selecting the menu item Properties in the context menu. Afterward, click on the tab Digital Signatures. In the signature list, click on the name Michael Thummerer and then on the button Details. There you will see whether the digital signature is valid and thus the file has not been modified.

SHA1 Checksum

The SHA1 checksum allows you to verify the integrity of the files and ensure that the file was transferred without errors and has not been modified by other programs.

CHM File

The documentation in CHM format can be opened directly by double-clicking without additional software.

PDF File
